Glossary
Adapter Board – A circuit board required to convert information to and
from an external device to the format required by the Main Control Board
microbus.
Analog – A control system with continuously adjustable voltage or current
level.
Binary – A numbering system using the base 2 Radix. The value can be 0
or 1.
Bit – One binary digit of data consisting of 0 or 1.
Default – Value provided for a parameter as part of the program when the
Drive is initially started.
Programming Terminal – Programming device used to enter and monitor
parameters in the Bulletin 1395 Drive.
Digital – A control system that uses two specific voltage or current signal
levels which correspond to 1 or 0.
Configuration Parameter – A variable that is used to pass values between
processes on a real time basis for Drive control.
Fault – A Drive condition that is monitored and displayed on the
Programming Terminal.
Firmware – The non-changeable portion of the software program that
defines relationships between the parameters.
Hardware – That portion of the software program that defines relationships
between the parameters.
Hexadecimal – Number system using the base 16, Radix.
Interface – Hardware and associated software designed by Allen-Bradley for
the exchange of digital information between microprocessor chips at the
microprocessor level. The microbus is used for transfer of information
between the control microprocessors located on the Main Control Board. In
addition, it allows for connection of two adapter boards through two ports.
Microbus – Hardware and associated software designed by Allen-Bradley
for the exchange of digital information between the microprocessor chips at
the microprocessor level. The microbus is used for transfer of information
between the control microprocessors located on the Main Control Board. In
addition, it allows for connection of two adapter boards through two ports.
Microprocessor – A silicon chip that can be programmed to process data.
Setup Parameter – A variable that is given a constant value for a specified
application.
